cable fault locator for RJ11/RJ45

1. Phone cable tester ( It is very easy and fast to find the fault wire among a large amount of wires )
1) Put the phone cable directly into the RJ11 interface;
2) Put the switch to " SCAN" , then the indicator "STATUS" will lighting , which means that the emitter is on normal operation.
3) Put down the work button on the emitter and press it , let the probe of the emitter test the target cable.
4) Compare the Volume of the "Beep" and indicator's degree of the light and dark , the one which is loudest and brightest is the target cable.
2.Network cable tester
Put the crystal head network cable into the RJ45 interface directly.
Put the switch to " SCAN" , then the indicator "STATUS" will lighting, which means that the emitter is on normal operation.
Put down the work button on the emitter and press it, let the probe of the emitter test the target cable.
Compare the volume of the " Beep " and indicator 's degree of the light and dark , the one which is loudest and brightest is the target cable.
3. Electronic cable tester
1)Connected the emitter and metal conducting cable by alligator clip;
2) Put the switch to " SCAN" , then the indicator "STATUS" will lighting, which means that the emitter is on normal operation.
3) Put down the work button on the emitter and press it, let the probe of the emitter test the target cable.
4. Open circuit/ short circuit testing
Put down the work button on the emitter and set the button to "TEST", and press the work button for two seconds until the flashing light turn to on. Put the Alligator clip into the RJ11, use the two clips of the alligator clip to grip the two sides of the testing area. If there is short circuit, the NO1. Light on the emitter will on , otherwise will not . The resistance of the wire can learn from the brighten level of the STATUS light: the brighter the light , the smaller the resistance; the darker the light, the bigger the resistance.
